Ytterbium is the 70th element on the periodic table.  It is a member of the lanthanide series at the bottom of the periodic table.  This means that it has f orbital electrons in its valence shell.  It is most commonly found in the +2 or +3 oxidation state.  It combines with halogens (F, Cl, Br, I) to form dihalides and trihalides.  As an example, YbCl2 is in the +2 oxidation state and YbCl3 is in the +3 oxidation state.  Ytterbium also forms oxides with oxygen.  Yb2O3 and YbO are the two types of oxides.
